Ingredients

Special equipment: 15 to 20 (10- to 12-inch) wooden skewers, soaked in cold water 1 hour

Preparation

Prepare grill for cooking. If using a charcoal grill, open vents on bottom of grill.

Rinse squid under cold running water and pat dry with paper towels. If squid are large, halve tentacles lengthwise and cut longer ones, if attached, crosswise into 2-inch pieces. Pull off flaps from squid bodies, if attached, and reserve. Cut each squid body lengthwise along "seam" and open flat. Score large squid, including flaps, lengthwise with a sharp knife, making cuts close together (about 1/8 inch apart like ridges on rigatoni) and being careful not to cut through squid, then halve squid bodies crosswise.

Toss squid with 3 tablespoons reserved dressing and salt and pepper to taste in a clean bowl. Toss arugula in another bowl with just enough of remaining dressing to coat, then season with salt and pepper. Divide arugula among 4 plates and top with squid. Serve with lemon wedges.
